as far as I know, it doesn't have HW raid in any meaningful sense
(that would be: does raid5 parity in hardware.)  it's just another
dual-channel udma controller that happens to have some bios support
for doing trivial raid (0,1).  there's no advantage over normal 
soft raid for these raid levels, since they don't eat CPU.

I don't believe there's any hpt 370 support problem with current Linux
(that means 2.4, of course; 2.2 hasn't seen IDE updates for some time now.)
